Impedance-controlled connectors have small profile
Hirose Electric
DH Series
Hirose has introduced the DH Series to provide solutions for applications needing impedance-controlled connectors in a smaller profile.
Although compact, the connector is robust and can achieve up to 2.5Gbit/sec of high-speed transmission, dependent on the cable type.
The range consists of IDC or solder-type cable-mount-type plugs and surface-mount receptacles in 17, 27, 37 and 51 contact sizes.
The structure of the connector features a durable D-shaped opening on the mating face of the plug and receptacle to resist against wrenching forces.
There is a choice of robust screw locks or user friendly one-touch locks available in metal or plastic to offer total design flexibility and secure locking.
The plug has contacts that are staggered on the first and second row, creating a unique contact arrangement for IDC termination, ensuring that each cable is clear of the other contacts.
The termination of the cable on to the IDC contact is a simple process with a dedicated tool available to allow all cables to be inserted and terminated in both rows at once.
Twinax or twisted-pair-type cable can be used in AWG 28 size.
The internal metal-shielded structure is easy to assemble and is said to have excellent shielding properties for EMI prevention.
The surface-mount receptacles are available in straight or right-angle versions with a 0.5mm fine mounting pitch to save space.
Through-hole solder posts from the outer shell maximise the retention and stability of the receptacle to the PCB board.
